UnverifiedRAG's anti-hallucination measure is to use system prompts to constrain answers to come solely from retrieved documents, requiring the AI to respond that there is no relevant information when the information is not present in the context.68% similarUnverifiedRAG and agentic retrieval can only retrieve what someone has written down, and review decisions are usually not written down by anyone, unless a tool turns it into a one-line command.66% similarUnverifiedThe information input boundary of RAG is locked in at the retrieval stage; if key information is missed during the retrieval step, no matter how powerful the subsequent generation stage is, it cannot compensate.65% similarUnverifiedThe system prompt requires all responses to cite sources, and when retrieval results are irrelevant, it must respond with 'I don't know.'64% similarUnverifiedWhen a tool returns an error or empty output, it should be rejected immediately rather than passing on incomplete data — this is a fail-fast handling approach64% similar
